Oh no question, more powerful, and the actual operation can be faster, i.e., copying a 50gb file in the CLI vs. graphical will be faster, but my point is, that it tends to be faster for navigating and executing simple operations with the file manager.
For instance in file manager, it, it takes me 5 double clicks to get to C:\Users\mike\AppData\Local\Docker and a 6th to open log.txt
versus:
type: notepad C:\Users\mike\AppData\Local\Docker\log.txt
Would you rather double click 6 times, or type 50 characters? That's assuming you know the destination you're going too. I can't speak for everyone but many times, I need to see where things are, like trying to find a file for opatch (an oracle utility)
I'm not saying terminal is bad, but there many tasks that are just much more simpler and easier using the windows file manager (or Finder)
That being said, at work, I tend to use the terminal to get some file maintenance done, simply because it is more powerful.
